It's the age old complaint.

As long as the price people are willing to pay is 
not the same as the prices everywhere, someone 
will pick it up cheap and sell it for more. It's 
the same concept as the stock market.

And yes, it's the same kind of people that play 
the stock market.

I can't offer any help, only the knowledge that 
I've been in the same spot as you are. The moment 
the show appears on CN, the prices more than 
triple almost overnight. 

Some people just see $$$ signs instead of cels.

If you don't mind sharing, what cel or what 
series did you lose?
